ACL rules Netgear Switch

I have Netgear switch XS748T connected to SonicWall firewall.

Created 3 VLANs on the switch (VLAN20, VLAN40 and VLAN50) and the routing is done on the switch.

All VLans are getting the internet and all working fine.

I am trying to allow VLan20 to access VLan40 and VLan50.

Allow VLan40 to access VLan50.

Block VLan40 to access Vlan20.

Block VLan50 accessing VLan20 and VLan40.

I tried everything according to all documents available on the internet and never worked for me.

I created the ACL rules and applied them to the ports, and nothing worked.

SonicWALL -  192.168.100.1 – connected to port 1 on the switch

Switch – 192.168.100.5

VLAN40 – 192.168.40.0 – Ports 41 and 42 - untagged

VLAN50 – 192.168.50.0 – Ports 43 and 44 - untagged

VLAN20 – 192.168.20.0 – the rest of the ports - untagged

See attached images if it helps.

Thanks..
